ROAS'IING APPARATUS.

' Specification of Letters l atent.

Application filed July 12, 1916. Serial N o. 108,787.

To all whom it may concern:

Be it known that I, ADoLF VVEIss, a citizen of the United States, and a resident of the borough of Brooklyn, county of Kings, city and State of New York, have invented certain new and useful Improvements in Roasting Apparatus, of which the following is a specification.

My improvements relate to apparatus used for roasting coffee, peanuts, grains or other natural products, and are designed to render the use and manipulation of such apparatus more safe, convenient and expeditious than heretofore, a distinctive feature of the invention being the provision of the roasting drum with hinged doors held in closed relation' normally by 'la-tches wvhich may be tripped as desired to open the doors and discharge the contents of the heated drum without removing or touching the latter manually, as hereinafter more fully set forth.

Figure l, is a front elevation of my improved roasting apparatus; Fig. 2, a top view thereof; Fig. 3, a transverse vertical section taken upon plane of line 33, Fig. 4; Fig. 4:, a central vertical longitudinal section of the casing, showing the other parts in elevation; Fig. 5, is a detail isometrical view of one of the latches; Fig. 6, is a-view of the drum or cylinder, showing the doors thereof; Fig. 7, is a sectional viewof the drum doors on a larger scale; Fig; 8, is a sectional elevation showing a modification in the form of tripping device.

O, represents the rectangular trunk or body of the casing supported upon legs or standards 0, 0, and provided with a hinged semi-cylindrical cover C, for which rearwardly projecting rests 0, c, are provided at the back of the trunk C, to support the cover C,-when raised. Open bearings 0 0 are formed on the side members of the casing C, on which the journals 655, (Z, of the cylindrical roasting drum D, rest, one of said journals being provided with a crank cl, or equivalent means whereby the said cylindrical drum D, may be rotated on its axis.

The roasting drum D, is formed with one or more doors (Z extending longitudinally practically the whole length of the cylinder. Preferably two such doors are provided, as shown more particularly in Figs. 6, and 7,

of the drawings, one overlapping the other so that the overlapping one will hold the other in place when closed and latched, said overlapping door being formed with protuberant studs or shoulders d (1 at either extremity for engagement with the latchesa, a, mounted upon the ends of the roasting drum D.

Obviously various forms of latch and trip mechanism may be employed for the purpose of securing and releasing the doors d 6F, and I do not limit myself in this respect to the identical form, construction or arrangement of parts herein shown since other mechanical expedients and equivalents may be substituted with like result and without departing from the spirit and intent of my invention. As shown however, by way of illustrating the principle involved, latches a, a, are pivotally attached, one to each head or end of the drum D, as at d, the outer end of the latch a, being formed with notch or Patented Jan. 16, 1917.

shoulder a, adapted to engage with the pro therewith by a retractile spring of, attached at one end to the latch a, and at the other to the end of the drum D, it being understood that these latches, etc., are duplicated at each end of the latter. The swinger play of each latch a, is limited and controlled by a strap d upon each end of the drum as indicated particularly in Fig. 3. Obviously when the door is, or doors are closed and the latches a, are in engagement with the protuberances (i the springs (4 will tend constantly to hold the parts in locked relationship so that the roasting drum D, may be rotated freely and continuously without danger of spilling the contents previously introduced throughthe open doors facing upward and with the cover C, thrown back for the purpose.

WVhen it is desired to release the contents of the drumD,.the latches a, arethrust back against the resistance of the springs o by trips t. which are caused to protrude into the paths of the outer ends of the latches a, as they rotate with the drum.

In Figs. 3, to 6, inclusive the free ends of the latches a, are shown as formed with lateral projections a to insure contact with trip arms t, projecting upward vertically from a trip-frame lever t, 'pivotally attached to brackets 0 0 on the trunk casing C, the inner cross bar F, of said trip-frame lever 11', resting normally upon a bracket or support 0*, on the inner side of said trunk casing C, see particularly Figs. 3. and Thus when the front cross member i of the trip-frame lever If, is depressed, the trip arms 6, will be projected into the path of the lateral projections a of the latches a, which latter, will consequently contact with the trips 6, as the drum'rotates, thus automatically releasing the door or doors d against the resistance of the springs so that the contents of the roaster drum-D, will be discharged by gravity into a receptacle R, placed immediately "below for the purpose, it being noted of course that the trip mechanism is so positioned as to release the door cr doors when the latter are inlowest position underneath the drum I).

In the modification shown in Fig. 8, the trips 25, t, consist of spring actuated bolts which may be released to protrude laterally into the paths of the free ends of the latches a, a. These trip-bolts t, are supported in fixed sleeves 25*, formed with longitudinal slots i with lateral offsets forthe accom-' modation of studs 5 on the trip-bolts 6, whereby the latter may be held back against the resistance of's rin s t until the tri s t, are set to intercept 'and' throw open the latches a, a, substantially as hereinbefore set forth in connection with the tripping mechanism shown in the other pr1or figure-sv of the drawings;

-C, is the front door of thetrunk body C, hinged to the latter and held in place by button fastenings a, 0*, or other mechanical expedients;

c c arethe handles ofthe trunk casing C;

c, is the usual vent hole inthe cover C, closed or controlled by the usual slide or damper 0 see particularly Fig. 2. The re ceptacle for the roasted products is also provided with handles 7', 1", and may be withdrawn from underneath the drum D, and trunk casing C, at either end of the latter between the legs a, 0.

The roasting drum D, is heated externally by any suitable means positioned within the trunk casing C, as by means of the twin gas burnersg, g, shown in the drawings, connected with a common gas head or supply conduit 9, which is connected in turn with a gas supply pipe, etc, in a manner well known in the art.

It will be seen that by my construction and arrangement of parts the contents of roasting drum D, may be quickly and conveniently discharged into thereceptacle R,

by simply setting the trips 25, t, to intercept and retract the latches a, a,and release the protuberances orshoulders d d on the doorcl", as indicated in dotted lines in Fig. 3. This setting of the trip mechanism may be accomplished externally, and without touching any heated part of the apparatus, whereas heretofore it has been customary if not absolutely necessary to unship and lift the drum out of its casing and to shake out the roasted products'prior. to recharging.

' By providing for theopeningof the door when the latter is in the lowest position under the drum I insurethe automatic discharge of'all thecontents ofthedrum;

and when the cover C, is raised and thedrum turned with the doorsupward the drum may obviously be quickly and conveniently charged with fresh material for roast- What I claim as my invention anddesire to secure by Letters Patentis,
